Cook thinly sliced roots and onions cut in rings with the spices for 5 minutes, let the carp or the carp filet steep (not cook) in this brew for 10 to 15 minutes. Take the carp out of the brew and put it on pre-warmed plates and garnish it with freshly grated horseradish. I recommend salt potatoes as a side dish.

HINT:
Instead of carp you can use any other fish.
Serve the fish brew as clear fish soup, with potatoes and vegetables and sprinkle with herbs.
